Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea,
and Tropical North Atlantic from 07N to 19N between 55W and 64W
and the Southwest North Atlantic including the Bahamas

...GULF OF MEXICO...

High pressure located over the SE CONUS extends a ridge across 
the Gulf waters producing a gentle to moderate anticyclonic 
flow. This is expected to continue across the Gulf the remainder 
of the weekend, with high pressure centered over SE Louisiana.
Moderate to locally fresh return flow will set up across the
western Gulf on Sun, ahead of the next cold front forecast to 
reach the coast of Texas Sun night. The front will move slowly 
across the NW Gulf through Mon night, reach from SE Louisiana to
near Tampico, Mexico by early Tue morning, and move back toward 
the coast of Texas Tue night into Wed.

...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...

A dissipating cold front extends from eastern Cuba to the Gulf
of Honduras generating scattered showers and thunderstorms W of
82W. Winds and seas could be higher near tstms. The most recent 
scatterometer pass indicates fresh to strong winds on either side
of the front, particularly from 15N-20N between 83W- 86W. This 
is the result of the pressure gradient between high pressure over
the SE CONUS and the front. These winds are forecast to diminish
to 20 kt or less by tonight. 

Winds are on increase across the south-central Caribbean as 
noted per the most recent scatterometer pass. Expect fresh to 
strong winds over the eastern and central Caribbean through Tue, 
with building seas of 10 or 11 ft near the coast of Colombia.

...SW N ATLANTIC INCLUDING THE BAHAMAS...

A cold front extends from 31N66W across the central Bahamas to 
eastern Cuba. The front combined with a weak 1012 mb low pressure
near 25N73W is generating scatterred to numerous showers and 
thunderstorms within about 90 nm E of front/low. Winds and seas
could be higher near tstms. Latest scatterometer data show fresh
to strong winds within 90 nm E quadrant of the low center, and
also N of 27N E of the front to 65W. Expect the front to become 
stationary from 31N64W to the SE Bahamas to E Cuba tonight. The 
surface low is expected to merge with the front tonight. The 
front will then gradually dissipate through Sun night.
